Moore-Marsden
Bob bought for $500K before marriage. After 6 years of mortgage payments together, how much does Alice get? We calculate every step.
Transmutation
Alice was added to the title in 2019. That single event increased her divorce settlement by $57,000. Here's why.
Watts & Epstein
Bob stayed in the house 18 months post-separation. Alice paid the mortgage. Here's who owes whom — and how much.
RSU / Nelson Formula
Alice has AAPL grants, Bob has META grants — some before marriage, some vesting after separation. The Nelson formula divides them correctly.
